Jalvaayu sanskriti gadhti: Bihu, Pongal, Baisakhi, Onam, Lohri, Makar Sankranti aur Chhath ritu aur fasal manaate. Arthvyavastha bhi: monsoon ki vifalta matlab kharaab fasal, paani ke liye lambi paidal yaatra, khet mazdooron ka shehar palaayan aur mehnga khaana; udyog ko bhi bharosemand mausam aur paani chahiye.

Charam mausam aapdaayein laata. Chakravaat tab bante jab samudra par tez kam-daab nam hawa kheenchta jo shaant, baadal-rahit aankh ke charon or ghoomti; Bharat ka poorvi tat sabse zyaada prabhaavit, aur IMD har ek par nazar rakhta. Baadh tab jab bhaari baarish ya uphanti nadiyaan sookhi zameen dhak leti; UP, Bihar, Kerala, Andhra aur Assam sambhaavit. Himalaya mein hims-jheel apni deewaar tod sakti: 2013 mein aisi baadh ne Kedarnath ke aas-paas tabaahi machaayi aur lagbhag 6,000 log maare gaye. Shehar tab doobte jab naale band ya concrete paani risne na de.

Bhooskhalan, chattaan-mitti ka achaanak girna, monsoon mein pahaadi raajyon aur Pashchimi Ghaat mein, jangal kaatne aur laaparvaah nirmaan se badhta. Jangal ki aag sookhi vanaspati mein failti, aksar insaani laaparvaahi se, vanya jeevon aur hawa ko nuksaan. NDRF (Raashtriya Aapda Pratikriya Bal) bachaav aur nikaasi ke liye prashikshit. Har aapda ke praakritik aur insaani kaaran, aur dono ghataaye ja sakte.
